<h1>NSObject(FSKRequestDelegate)</h1>

The FSKRequestDelegate category on NSObject defines
FSKRequest delegate methods that can be implemented by
objects to receive informational callbacks about the asynchronous
load of a FamilySearch API request.
<br><br></p>
<p>Note that all these will be called on the thread that started
the asynchronous load operation on the associated FSKRequest
object.
</p>
<p>The following contract governs the delivery of the callbacks
defined in this interface:
</p>
<ul>
<li>Before receiving a response or processing a redirect,
<tt>request:didReceiveAuthenticationChallenge:</tt> may be
received if authentication is required.
</li>
<li>Unless a FSKRequest receives a <tt>-cancel</tt> message,
the delegate will receive one and only one of
<tt>-request:didReturnResponse:</tt>, or
<tt>-request:didFailWithError:</tt> message, but never
both. In addition, once either of these callbacks is sent, the
delegate will receive no further callbacks of any kind for the
given FSKRequest. 
</li>
</ul>
